Дана таблица из чисел, надо найти разность минимальных путей от верхней границы до нижней и от левой границы до правой. Для движения от верхней границы возможны только движения: вправо, вниз и влево. Длина пути считается так: сумма всех чисел в клетках через которые мы проходим. Для движения от левой границы к правой возможны движения: вверх, вниз и вправо. Путь от верхней границы до нижней — это путь начинающийся в любой из клеток первой строчки и заканчивающийся в любой из клеток последней строки таблицы. В ответ выведите разность длины минимального прохождения квадрата сверху вниз и слева направо(разность найденных минимальных путей).

Пример для таблицы 4 на 4:

40,35,13,32
60,58,40,20
83,18,11,53
72,50,85,75

Длина минимального пути сверху-вниз: 13+40+11+18+50 = 132. Длина минимального пути слева-направо: 40+35+13+32 = 120. Разность 12.

Найдите разность для таблицы размера 40 на 40:
